Abstract
1404631 Filter element NOEL MARQUET & CIE SA 2 Nov 1972 [9 Nov 1971] 50489/72 Headings BID and BIT A filter element for air or liquids comprises a sheet 2 of porous filter material held under tension in frame 1 of plastics material which has been applied to the filter material when in a flowable state so that it penetrates through the filter material and, when set, forms an airtight mass. The frame and filter material are further interconnected by longitudinal and transverse struts of plastics material which similarly penetrate through the filter material. The filter material is extended 6 past the frame to form a seal between the element and the support 14 or 16 in which it is to be mounted. This extension of filter material may be used, in addition to flexibly connect a series of consequetive framed filter elements formed on a web of filter material (Fig 6, not shown). The filter material may be in the form of a flat sheet or have the form of at least part of a cube, sphere, cone, truncated cone or cylinder provided with a frame adjacent the or each edge. The filter material used may be flexible, e.g. fleeces, cloths, braided or woven metal threads or plastics foam or may be rigid, e.g. perforated metal or gauzes. The plastics frame may be flexible or rigid, thermoplastics foam material being preferred. The frame may be internally strengthened by non-plastics strengtheners, e.g. wire. Several sheets of filter material may be clamped together in one frame as shown in Figures 1 and 2.

Claims (5)
1. A filter element comprising a sheet of flexible, filter material; an outer frame and additional struts of synthetic resin, wherein the sheet is held under tension in the frame and extends in at least one direction far enough through the frame for enabling the projecting filter material o form a seal find wherein the resin of the frame and the struts homogeneously penetrates through the sheet towards both sides ΘΟ that the frame and the struts form a homogeneous unit with the sheet.
2. A filter element as claimed in olaiin 1 and 2, wherein the longitudinal and transverse struts are made of the same material as the frame and are produced in the sama manufacturing operation.
3. 5. A filter element as claimed in any preceding claim, comprising a web of filter material on which there are at least two supporting frames with longitudinal and/or transverse struts, the framies being disposed adjacent one another along the length of the web of filter material and epaoed at suoh a dis anoe from each other in relation to the' thioknoss of t e xVaino' iiiembore tlat t o filter 40745/2 element oan be, folded through an angle in the region of 180°.
4. A filter element as claimed in any preceding claim, in which the filter material is in the form of part of either a cube, 'or a sphere, or a cylinder, or a tube, or a cone, or a truncated cone and the, or at least one, edge thereof is inserted iril corres ondingly shaped supporting frame.
5. Λ filter element as claimed in any preceding claim, in which there are additional strengtliening members embedded i the said plastics material frame in whioh the filter material is embedded. S* A filter element as claimed in any of claims 5 to 5i in which the plastics material of the frame and/or the longitudinal struts and/or the transverse struts is a rigid and/or a flexible plastics material. •7. A filter element as claimed i any preceding claim, in which the frame is provided with spacer projections. 8 A filter element as claimed in any preceding claim, in which the frame and/or the struts is or are formed of a foamed or non-foamed thermoplastics synthetic material or such foamed or non-foamed synthetio plastic materials as have boon formed during shaping by molecule enlargement from monomeric or corresponding preproducts. 9u, A filter element as claimed in claim in which the frame and/or the struts is or are formed of a polyurethane integral foam. 10· A method of manufacturing a filter element as claimed in any preoeding olaim, comprising the steps of clamping a selected material in a suitable tool and thon injecting under pressure a mixture of polyurethane starting components and corresponding1 additives to produce an integral foam through one or more inlet apertures into the tool and allowing them to react while maintaining the conditions necessary to produce the integral foam.
